[PATCH] tests/kms_flip: Fix regression on non-Intel devices in event_loop

[Alex Hung <alex.hung@amd.com>]

Guard the device-id query with is_intel_device() so the "wa" flag is
only computed on Intel hardware, restoring the pre-regression behavior
for all other drivers.

This fixes the following regression:

(kms_flip:15463) intel_chipset-CRITICAL: Test assertion failure function intel_get_drm_devid, file ../lib/intel_chipset.c:145:
(kms_flip:15463) intel_chipset-CRITICAL: Failed assertion: is_intel_device(fd)

Fixes: 2a9f1c1ae ("tests/kms_flip: test suspend at most twice on SNB && BMG")
